Question 1

What are peptides?

Accepted Answer

Peptides are short chains of amino acids synthesized for use in laboratory and scientific settings. They are used to study biological processes, mechanisms of action, and potential therapeutic applications. All peptides listed on this site are strictly for laboratory and educational use only and are not intended for human consumption.

Question 2

Are these peptides legal to purchase?

Accepted Answer

In the United States, most peptides can be legally purchased for laboratory use. They are not FDA-approved for human therapeutic use. Laws vary by country, so buyers should verify their local regulations before purchasing. These products are sold for laboratory and educational purposes only.

Question 3

What is the difference between peptides and pharmaceutical drugs?

Accepted Answer

Pharmaceutical drugs have completed clinical trials, received regulatory approval, and are prescribed for specific medical conditions. These peptides have not completed this regulatory process and are not approved for therapeutic use. They are used in preclinical studies to investigate potential biological mechanisms and effects.

Question 4

Do you sell directly?

Accepted Answer

No. This site is an informational resource that curates product information and links to our trusted vendor. When you click "Buy Now," you are directed to our vendor's website where your purchase is fulfilled.

Question 5

What does 99%+ purity mean?

Accepted Answer

Purity refers to the percentage of the compound that is the intended peptide vs impurities, byproducts, or residual solvents. 99%+ purity means at least 99% of the compound by mass is the target peptide. This is verified through HPLC (High-Performance Liquid Chromatography) testing by independent third-party laboratories.

Question 6

What is a Certificate of Analysis (COA)?

Accepted Answer

A Certificate of Analysis is a document from an independent, accredited laboratory confirming the identity, purity, and potency of a compound. Our vendor provides a COA for every batch they produce. You can request the COA for any product before or after purchase. The COA confirms the peptide is what it claims to be at the stated purity level.

Question 7

How are peptides tested for purity?

Accepted Answer

Independent laboratories use HPLC (High-Performance Liquid Chromatography) to measure compound purity and Mass Spectrometry (MS) to confirm molecular identity. These tests confirm both the purity percentage and that the correct peptide sequence was synthesized. Reputable vendors use third-party labs for these tests rather than in-house facilities.

Question 8

Should I be concerned about peptide quality from other vendors?

Accepted Answer

Quality varies significantly across the peptide market. Common issues with lower-quality suppliers include underdosing, incorrect peptide sequences, high impurity levels, and no independent verification. We recommend only purchasing from vendors who provide third-party COAs from reputable labs. Always request and review the COA before purchasing.

Question 9

How do I place an order?

Accepted Answer

Click "Buy Now" on any product page. You will be redirected to our vendor's website where you will complete your purchase directly on their platform. They accept major credit cards and other payment methods. Orders are typically processed and shipped within 1–2 business days.

Question 10

How long does shipping take?

Accepted Answer

Our vendor ships from within the United States. Standard shipping typically takes 3–7 business days. Expedited options are available at checkout. Orders are shipped in discreet packaging for privacy. International shipping options may vary — check the vendor's website for current options.

Question 11

Is packaging discreet?

Accepted Answer

Yes. Our vendor ships in plain, discreet packaging with no identifying product information on the exterior. This ensures your privacy and prevents any issues at delivery. Products are typically shipped in padded envelopes or small boxes with only a return address and standard carrier labels.

Question 12

What is the return policy?

Accepted Answer

Return and refund policies are determined by the vendor, not this website. Please review their current return policy on their website or contact their customer service team directly for any order-related issues. Most reputable vendors offer a satisfaction guarantee on unopened products.

Question 13

How do I reconstitute a lyophilized (freeze-dried) peptide?

Accepted Answer

Most peptides are supplied as a lyophilized (freeze-dried) powder and must be reconstituted with bacteriostatic water (BW) before use. Use a sterile syringe to slowly inject BW into the vial along the side wall (not directly onto the powder). Gently swirl — do not shake — until fully dissolved. Common reconstitution: 2mg peptide + 2mL BW = 1mg/mL concentration.

Question 14

How should peptides be stored?

Accepted Answer

Lyophilized (unreconstituted) peptides should be stored in a cool, dark place — a refrigerator (2–8°C) is ideal. Once reconstituted, peptides must be refrigerated and used within 28–30 days. For long-term storage of lyophilized peptides (3–6+ months), a freezer at -20°C is recommended. Avoid repeated freeze-thaw cycles which degrade peptide integrity.

Question 15

What is bacteriostatic water and where can I get it?

Accepted Answer

Bacteriostatic water is sterile water containing 0.9% benzyl alcohol, which prevents bacterial growth in the solution after it has been opened. It is the recommended diluent for most peptides. It can be purchased from laboratory supply companies. Do not use tap water, distilled water, or regular sterile water (which goes bad quickly after opening).

Question 16

How long does a reconstituted peptide remain viable?

Accepted Answer

Once reconstituted with bacteriostatic water, most peptides remain stable for 28–30 days when refrigerated at 2–8°C. Some peptides are more stable than others. To maximize viability: keep refrigerated at all times, avoid light exposure, use sterile needles for every draw, and never leave reconstituted peptides at room temperature for extended periods.
